NEW CHALLENGE GRANULATED FERTILISERS AT NO EXTRA COST TO THE FARMER, ALL CHALLENGE PHOSPHATIC FERTILISERS SUPPLIED BY TE PAPAPA, OTAHUHU AND MORRINSVILLE WORKS ARE NOW PROCESSED THROUGH GRANULATING PLANTS. These Challenge fertilisers will be free-flowing and granular, but NOT entirely powderfree.

BETTER, FASTER GROUND SPREADING The variation of particle size and weight gives both better coverage and increased swath widths with all types of ground spreading units.

BULK OPERATORS REPORT — Handling efficiency is greatly improved with these free-running fertilisers. Bulk operators who have used Challenge's new products this season report increased loading, spreading and turn-round speeds. Wasteful, time-consuming, build-up of fertiliser on topdressing machines is virtually eliminated. By cutting maintenance time Challenge helps farmers get more fertiliser on the ground during the peak-demand periods.

TIME & COVERAGE ECONOMIES IN AERIAL TOPDRESSING Aerial operators have also welcomed the free-flowing, easy-to-handle advantages of granulated Challenge fertilisers. They are now able to place fertiliser more accurately — and from a greater height. By increasing their safety margin the new products enable them to cut down weather delays. It's quite practical to topdress with Challenge granulated in wind-conditions which, with the old-type powdered fertiliser, would mean fertilising half the next county.

AERIAL SUPER TO BE DISCONTINUED Because of new Challenge granular fertiliser's outstanding handling and storing qualities Aerial Super will be discontinued. Farmers aerial topdressing with Challenge Superphosphate containing 9% Phosphorus get better value in comparison with 8% Phosphorus Aerial Super, and 7% Phosphorus Serpentine Super. Phosphorus costs per unit ex works:- In Superphosphate………. £1 2 10 In Aerial Super………. £1 5 5 In Serpentine Super………. £1 8 7

SPECIAL MIXTURES AVAILABLE Challenge's special mixture service is still available. All standard fertilisers, namely those containing 15% and 30% Potash, Cobalt Sulphate, Copper Sulphate, Sodium Molybdate etc. now have a Superphosphate base and are granular. Serpentine Super and all mixtures with Serpentine Super base are still available as special mixtures for those areas where Magnesium is recommended. Supply of Challenge granulated fertilisers is limited to the Auckland Provincial area bounded by Wellsford in the North and Te Kuiti in the South.
